Geoffrey Jacoby commented on PHOENIX-3611:
------------------------------------------
Thanks for catching the typo, [~apurtell]. Any suggestions on a better default
max size for the cache? [~jamestaylor] ?
> ConnectionQueryService cache should expire LRU entries

> Key: PHOENIX-3611
> URL: https://issues.apache.org/jira/browse/PHOENIX-3611
> Project: Phoenix
> Issue Type: Improvement
> Affects Versions: 4.8.0, 4.9.0
> Reporter: Geoffrey Jacoby

>
> Currently the cache of ConnectionInfo/ConnectionQueryServicesImpl can hold
> its entries forever. This can potentially lead to orphan cache entries, and
> since each ConnectionQueryServicesImpl object has an HConnection, it can also
> lead to leaked connections.
> Due to the way that ConnectionInfo hashing works (see PHOENIX-3126 and
> PHOENIX-3607), this is particularly likely on a secure cluster.
> The cache should be changed into an LRU-style cache with a fixed size and
> gradual expiration.
